tsdown-dist-layout-in-tests

tsdown-dist-layout-in-tests is a cursor rule for Cursor from prisma/orm. It costs 10 tokens per session (187 once invoked), scanned A, original, Apache-2.0.

A testing rule for mapping TypeScript imports to files produced by tsdown, a TypeScript build tool. It accounts for declaration files being placed directly in the dist folder.

In plain words
What is it for?
It helps maintain temporary tsconfig files and integration tests that resolve built package files correctly.
Why use it?
It prevents test imports from breaking because they expect declarations in the wrong folder after a build-tool migration.

About the project

Prisma ORM is a Node.js and TypeScript database toolkit that lets applications work with databases through a programming interface instead of writing every query directly in SQL. Developers use it with databases including PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, MongoDB, and CockroachDB. The catalogue add-ons provide agent rules, skills, hooks, agents, and other workflows for using Prisma.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tsdown-dist-layout-in-tests scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

tsdown dist layout for test path mappings

When packages are built with tsdown, declaration outputs are emitted in the package dist/ root as .d.mts files (for example dist/types.d.mts), not under dist/exports/*.d.ts.

Rules

  • In temporary tsconfig fixtures used by tests, map package paths to dist/*.d.mts or dist/*.
  • Do not assume dist/exports/ exists unless the package explicitly emits that structure.
  • Prefer wildcard mappings (dist/*) for subpath imports that may include both .mjs and .d.mts outputs.

Why

  • Prevents module resolution failures after tsup -> tsdown migrations.
  • Keeps integration tests aligned with the actual package export artifact layout.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
